Even things as small and seemingly mundane as street signs can represent a lengthy undertaking in the MMO development process. Shroud of the Avatar devoted a section of its most recent newsletter to talk about how the team took suggestions for street names and the difficulty of adding them with their proper signage.
Shroud of the Avatar is preparing to unleash Release 17 on April 30th. In addition to its dev-added enhancements, it will host various community-run events, including a scavenger hunt and a play written and performed by players. Before that happens, however, you might want to watch the following post-mortem of Release 16 as well as a studio tour of Portalarium.
